I I Application filed August 25, 1906. Serial No. 275,755.

To all whom, it may concern:

Be it known that I, JOHN J. Voonnnns, a citizen of the United States, residing in J ersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Fabric Belts for Conveyers,

' of which the following isa full, clear, and exact specification.

y invention relates to certain new and useful improvements in composition fabrics; and it consists of the novel features hereinafter described.

My composition fabric is adapted to use in' many ways; but it'is particularly valuable for use in belts for conveyors and the like wherein a strong flexible material is desired resistance to surface having a maximum Conveyer-belts, as will be readily understood, must possess a maximum power of comparatively thin and 0 resistance against wear which takes place when heavy material-such crushed rock, and the likefalls u on amoving belt from a placeof rest. hey must likewise possess sufficient flexibility to readily pass around the drums or pulleys upon which they travel and for this pur ose must be made flexible material. My invention will be found to possess the u'alities of great resistance to friction and exibility and strength, and in the drawings accompanying this specification I have illustrated several forms thereof.

Broadly speaking, it consists in providing a belt material, preferably one wherein one or more layers of woven fabric are employed to give longitudinal or cross-sectional strength, with a friction-surface which consists of the ends of cotton or other fibers, a cementing medium being employed to'bind the parts together. It will be understood that the friction-resisting qualities of a fiber is many times greater upon the end thereof than in cross-section, and therefore a belt having the contact thereon only will be proportionately more durable. j

In the drawings,

Figure 1 is a top view of a belt; and Fig. 2,a

section thereof, showing I the disposition of the woven fabric and fibers.

of a further modification Fig. 3 1s a fragmentary section of a modified form ofniy invent1on.-

Fig. 4 is a top view ofmy invention, and Fig. 5 is a. sectional view taken on lines 5 5 of Fi .4.

In Flgs. l and 2, 1 represents the cementing as ore, coal medium, which may be rubber or any other similar substance or composition. 2 represents one or more layers or plies of fabric serving to give longitudinal and cross-sectional strength to the belt. These plies are entirely embedded within the cementing material and'are cemented together thereby and are preferably disposed near the under surface or pulley-surface of the belt. construction of Fig. 2 above the longitudinal layers of woven fabric are arranged Vertical fibers of cotton or other suitable material entirely embedded within the cementing ma- In the terial and cemented in theirposition thereby,

the vertical members being preferably separated from the woven fabric by the cementing material. When so disposed, as will be readily seen, the upper fibers project their ends only toward the wearing or ,upper surface of the belt, and the frictional wear and tear thereon takes place upon the ends only and to a much less extent than is the case were the fibers subjected to a sion.

In Fig. 3 I have shown a modified form of my invention. In this construction I employ one or more layers of woven fabric for longitudinal and cross-sectional strength, likewise the cement-ing medium, such as rubber. In the cementing medium above the fabric I employ strips of fabric out on the bias and embedded within the material. The

bers are thus set diagonally. but practically cross-sectional abratake what wear occurs from the friction upon 7 their ends as desired. Y

In the constructions shown in Fi s. 4 and 5 instead of dis osing the vertical flbers uniformly throughout the belt I show them arranged in clusters, which may be made of any desired size and disposed as closely as may be required. These clusters may be formed of individual vertical fibers or flat tapes of fibers wound around to the desired size; but asubstantial part of the fibers must project vertically, so as to take the wear and tear of the surface friction upon the ends of the fibers.

What I claim, and desire to secure by Letters Patent, is

1. Asa new article pf manufacture 'a composition fabric comprising a cementing medium, a woven fa and extending longitudinally thereof, and a fibrous material also embedded therein, the

fibers of the latter being arrangedinpianes ric embedded therein I dium having scribed.
